BUTTE R-WORKER.

SPECIFICATION forming part of Letters PatentNo. 268,536, dated December 5, 1882.

Application filed June 9, 1882. (No model.) V

simple and efficient power butterworker,

whereby hand-labor may be superseded.

. Reference is to be had to the accompanying drawings, forming part of this specification, in

' which similar letters of reference indicate corresponding parts in both the figures.

- Figure l is a plan view of my improved butter-worker with a part of the cover employed for iuclosing the gearing above the table broken out. Fig. 2 is a sectional elevation of theimproved butter-workerwith the aforesaid cover shown in dotted lines.

A represents a circular concave table lnoun ted on a vertical pivot, b, set-upon any approved bench, d, or other support for an axis around which the table may revolve, the said pivot being stationary.

e represents a toothed bevel-wheel attached to the under side of the table, for turning it by a driver,f, to the shaft of which the power is to be applied by a driving-belt and a puller, g.

()n theuppersideof thetable is another toothed wheel, h, for giving motion to the conical rollers 'i andj by the pinions 7c,the said rollers being mounted by their outerjournals in boxes l, that are capable of shifting up and down in the slotted standards m, and by the journals of the other ends in the bearing-bar n, fitted on the vertical rod b, and being capable of shifting up and down on it, and also being secured anywhere by a setscrew; but its adjustment will be limited to the range of adjustment that the teeth of the Wheel h and the pinions will allow.

A cover, 0, of sheet metal or other approvedmaterial, incloses the pinions 7c and wheel It to prevent the butter from working onto them,

and one or more passages, 19, allow the butter,

milkto escape through thetable into the pan q, arranged on the bench 01 under the table to receive it, and having central vertical tubular extensions, it, around the rod 01. Over the pan is a collar, 2!, to be fastened on the rod by a setscrew or other means, for the hub ofthe wheel a and tableA to rest and revolve on. Near the outer edge the table also rests on anti-friction rollers o for supportand for being carried.

1n practice the wheels 0 and It may be constructed in one wheel having a double-toothed rim and being constructed with spokes in the common way, the said wheel being .let into an opening formed in the table suitable for it.

The table may have a rim rising up from the outer edge, if desired, to prevent the butter from being forced over the edge by the rollers; but it made sufficie-ntly concave the rim may not be required.

With a machine of the above-described character the laborious methods of working butter by hand may be avoided, the said machine being competent; to do all the work with a little attention quite as well as by hand and much more rapidly.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters lzatcn t, is-

1. The combination, with a table dished toward the center and loose upon a fixed vertical shaft, of a smooth conical roll, i, and a fluted conical roll. j, both revolved on their axes while the table is revolved under them,

as described.

2. In a butter-worker the crown-wheels h e clamped respectively to the top and bottom of the table A, to connect the cone-pinions lc'witll the drive-wheelf, as described.

3.The combination, with the fixed vertical rod 12 and the cone-driving pinions 7c Ir, ol' the horizontal barn, arranged at its middle loosely on said rod, b, and provided at each. end with a bearing for the journalsot' said pinio'nsk, as shown and described. ELMER U. RIGBYJ Witnesses:
